I create many images with TikZ and I would like to make an image gallery. It should look like this:
The gallery should
- put the image in front of a (gray) background
- resize the image to a maximum width / height (and leave the aspect ratio intact)
It would be nice if I could put the images in seperate files and use something like
\begin{gallery}
\input{tikz/myImage1.tex}[Some title]
\input{tikz/myImage2.tex}[another title]
\input{tikz/mathImage.tex}[This is a visualization of $f(x, y) = x^2 y^2$]
\end{gallery}
This is what I've got so far (code also at GitHub):
\documentclass[a4paper,12pt]{article}
\usepackage{amssymb,amsmath} % needed for math
\usepackage{standalone} % needed for includestandalone
\usepackage[utf8]{inputenc} % this is needed for umlauts
\usepackage[ngerman]{babel} % this is needed for umlauts
\usepackage[T1]{fontenc} % this is needed for correct output of umlauts in pdf
\usepackage{adjustbox}
\usepackage{xcolor}
\definecolor{myLightGray}{HTML}{F9F9F9}
\definecolor{borderColor}{HTML}{CCCCCC}
\usepackage{tikz} % needed for includestandalone
\usetikzlibrary{arrows,positioning, calc}
\tikzset{
pil/.style={->,thick}
}
\newenvironment{gallery}{}{}

\adjustbox{width=4cm,height=4cm,keepaspectratio,bgcolor=myLightGray,cfbox=borderColor 1px 0px 2px}{\includestandalone{equilateral-triangle-heights}}
\end{gallery}

Which produces:
I've used \includestandalone, but with this I had to add the style defined in \tikzset in dot-product-1.tex to the main document. Thats not good.

To horizontally align the content in the gray rectangle use
center=4cm, which will force an official width of 4cm and horizontally center the content in it without doing any further scaling. The vertical alignment can be done usingvalign=Mfollowed by aset vsize={2cm}{2cm}. Alternatively you can also useraise={.5\depth-.5\height}{2cm}{2cm}. Note that both will align the middle of the boxes at the baseline, which is fine here, but you might want toraise=2cmit in other cases.It looks like this:
